Open registration forms attract bots, and fake accounts are tedious to clean up.
The Login & Signup block in Nexter Blocks Pro can check every signup with Google reCAPTCHA before the account is created.
For every Login & Signup setting in one place, see the Login & Signup block guide.
Before You Start
- Edition: Pro — the Login & Signup block is part of Nexter Blocks Pro.
- Block to enable: Login & Signup, switched on under Nexter > Blocks in your WordPress dashboard.
- Registration switched on: in Settings > General, tick Anyone can register.
- reCAPTCHA v3 keys: register your domain (without http:// or https://) in the Google reCAPTCHA admin console. See Google’s reCAPTCHA v3 documentation.
Save Your Keys in Nexter
- Go to Nexter > Nexter Blocks > Settings.
- Turn on Connect Google reCAPTCHA and click its settings icon.

- Paste your keys into Site Key reCAPTCHA v3 and Secret Key reCAPTCHA v3, save the popup, then save the settings page.
Add reCAPTCHA to the Form
- Add the Login & Signup block to your page and click Design from Scratch.
- In the Forms panel, set Type to Register.

- Choose a Layout: Inline Form shows the form on the page, Button opens it from a toggle button.
- Open the Register tab, click + Add Field and choose reCAPTCHA in the Field dropdown.

- Choose where the badge sits with Position, then save.
How It Behaves
- reCAPTCHA runs quietly in the background when someone submits the form.
- The token is checked with Google using your secret key before the account is created, so failed checks never create a user.
- The same keys are used by every Nexter Blocks form on the site.
Limitations
- Pro only.
- Use reCAPTCHA v3 keys. The settings fields are labelled v3 and the registration form expects that version.
- Keys are saved once for the whole site, not per form.
Troubleshooting
Signups fail the check every time
Check the site key and secret key belong to the same reCAPTCHA registration, and that your domain is listed in it.
The reCAPTCHA badge does not appear
Turn on Connect Google reCAPTCHA in Nexter > Nexter Blocks > Settings and save the keys.
